Preliminary assessment of microplastic in rhizosphere and non-rhizosphere region of mangrove at four locations along Karachi coast, Pakistan.

Mangrove ecosystem faces significant threats from the various pollutants including microplastic (MPs). The aim of this study was to assess variations in MP distribution in mangrove sediments of rhizosphere (R) and non-rhizosphere (NR) regions. A total of 14,960 MP particles were identified from Sandspit backwater (SS-1 & SS-2) and Creek areas (PQ & KC).

Planiliza lauvergnii (Eydoux & Souleyet, 1850), a senior synonym of Planiliza affinis (Günther, 1861) with a re-evaluation of keeled back mullets (Mugiliformes: Mugilidae).

The taxonomic status of the keeled back mullets (Teleostei: Mugilidae) has been reinvestigated. Two nominal mugilid species having keeled backs from East Asia: Mugil lauvergnii Eydoux & Souleyet, 1850 and Mugil affinis Günther, 1861 have been re-evaluated through examination of the holotypes and fresh specimens. Comparison of morpho-meristic characters of the holotypes shows that both species are identical.

Bioassay Directed Fractionation of Petroleum Ether Extract of Aerial Parts of Ceriops tagal: Isolation of Lupeol as the Nematicidal Agent against Cyst Nematode Heterodera zeae.

Plant parasitic cyst nematode Heterodera zeae is a pest, causing substantial economic losses in agriculture. Organic pesticides, based on plant products have emerged as eco-benign nematicidal agents. Ceriops tagal is a well-known marine medicinal plant which has not been evaluated against any nematode.
